Researchers at the Eindhoven University of Technology in the Netherlands have created what they call the tiniest temperature sensor that is powered by the same wireless network it uses to communicate data. The sensor measures 2 square millimeters and needs no physical connection to...

The Minibot is a small autonomous robot vehicle that uses phototransistor that can detect lightness patterns on the ground to follow the edges of the dark lines. It has a MC9RS08KB4 MCU, coin cell, motor, and a phototransistor. The MC9RS08KB4 is part of the MC9RS08KB12 series, a...

Rui Santos @ andomnerdtutorials.com has tipped us with his latest project. In this project Rui connects two ESP8266 modules and sends data from 3 sensors to an Excel spreadsheet. The process is explained in detail and some prior experience with ESP8266 is necessary and provided in...
